Responsibilities

  • Contribute to offensive cyber research initiatives, including vulnerability exploration, capability prototyping, and analysis of modern and embedded systems
  • Develop and maintain offensive security tools, red-team automation frameworks, and mission-oriented software components
  • Support reverse engineering tasks across binaries, firmware, and hardware-adjacent systems to understand behavior, identify weaknesses, and inform capability development
  • Assist in designing and evaluating evasion-resistant payloads, covert communication mechanisms, and persistence techniques for realistic adversary simulation
  • Prototype automation and AI-driven approaches for reconnaissance, decision-making, and red-team workflow acceleration
  • Analyze adversarial tactics, techniques, and procedures (TTPs) to support realistic threat emulation and capability design
  • Collaborate with other engineers, hardware researchers, and mission teams to integrate software, embedded, and AI-driven components into cohesive research prototypes
  • Document research findings, prototype behavior, and operational concepts for technical and operational audiences
  • Participate in internal red-team exercises, capability evaluations, and iterative testing cycles to refine tools and methodologies
  • Stay current with emerging offensive techniques, hardware-assisted attack vectors, and adversarial AI research trends

Qualification

Required

  • Bachelor's degree in Computer Engineering, Computer Science, Cybersecurity, or related field. Degree must be completed by start date
  • Strong programming experience in C/C++ and Python, with demonstrated ability to build offensive tooling or low‑level software
  • Experience with reverse engineering fundamentals, including firmware analysis, hardware interfaces, or binary inspection
  • Hands‑on experience with red‑team operations, penetration testing, or adversary simulation
  • Familiarity with embedded systems, microcontrollers, or FPGA‑based development
  • Understanding of networking fundamentals, security vulnerabilities, and common attack techniques
  • Ability to communicate technical concepts clearly in both written and verbal formats
  • Demonstrated initiative through research projects, open‑source contributions, or published work
  • US citizenship is required
  • Ability to obtain and maintain a Top Secret/SCI with Polygraph clearance

Preferred

  • Active TS/SCI security clearance with Polygraph
  • Experience developing or modifying offensive security tools
  • Familiarity with EDR evasion concepts, covert communications, or payload staging
  • Experience with hardware security research, side‑channel analysis, or hardware Trojan detection
  • Background in AI/ML applied to cybersecurity (e.g., neural architecture search, AI‑assisted detection, agentic tooling)
  • Exposure to reverse engineering tools such as Ghidra, Binary Ninja, or IDA Pro
  • Experience with embedded debugging interfaces (JTAG, UART, SPI) or firmware modification
  • Contributions to security research communities, publications, or open‑source offensive tooling
  • Familiarity with cloud environments, containerization, or DevOps workflows
